Why the WIA has formed the In-Building Forum

In-building wireless networks are critical components of today’s wireless infrastructure.
These systems use a variety of network architectures and spectrum bands to extend cellular
service inside stadiums, commercial buildings, hotels, convention centers, hospitals,
university campuses, airports, and other large buildings. Private wireless, small cells
and DAS, and Wi-Fi can all be used to extend coverage and capacity across venues and campuses.

In-building connectivity is crucial because:

-80% of data traffic takes place indoors.
-Nearly 50% of Internet traffic comes from a mobile device.
-80% of 911 calls are made from cellphones.
-Building and operating in-building wireless networks accounted for $567 million in spending
in 2022 in the US. This includes spending on DAS, indoor small cells and private LTE/5G
networks by enterprises but does not include any spending on Wi-Fi networks. Construction
of in-building networks generated nearly $274 million in spending, while operating those
networks generated $293 million in spending.
